Force Domain Controller Removal

If the domain controller hosts any operations master (also known as flexible single master operations or FSMO) roles or if it is a Domain Name System (DNS) server or a global catalog server, warnings appear that explain how the forced removal will affect the rest of the environment. After you read each warning, click Yes. To suppress the warnings in advance of the removal operation, type /demotefsmo:yes at the command prompt. If you forcefully removal AD DS from a server that hosts an operations master role, you must seize the role after the Dcpromo operation. For information about seizing an operations master role, see Seizing an operations master role.
